Mental concentration is a difficult exercise which requires preparation. This preparation consists first in calming ourselves, because an agitated state disperses psychic energies. If we attempt to concentrate without having first established inner calm, we shock the cells of our brain and prevent them from doing their work properly. Every object has a natural inertia, and we cannot stimulate a desired movement all at once. We must start with a very gentle push, and only after a certain time will it assume on its own the momentum we wish. Never forget that the cells of our organism are living creatures, which we must neither force nor shock. Once we have achieved this calm we can begin to mobilize our cells in the desired direction. But here again, we need to learn how to proceed. When we start up the engine of our car, we do not immediately accelerate to 100 km per hour. Well, our minds also proceed in successive steps until we feel that mentally we have the situation sufficiently under control to concentrate on a chosen subject. Then we will notice that all our cells are collaborating in our work. We have given these cells such a good orientation that our mind naturally follows the direction we have chosen.
